Outline of Research at the Start

安定同位体は、ヒトの体内での蛋白代謝動体を評価できる方法で、海外では放射活性物質で蛋白をラベルする方法が実施可能であるが、我が国ではできないため、この安定同位体方が唯一の実験手段である。家族性高コレステロール血症(FH)はLDL高値が注目されているが、こう動脈硬化性リポ蛋白であるHDLが低く、これがFHの心血管リスクをさらに高めることがわかっており、低HDL血症の病態解明が必要である。加えて、HDLは濃度(量)ではなく機能(質)が重要との認識が高まっており、FHにおいてHDLの質の異常の検討も重要である。本研究では、FHでの低HDL血症の病態をHDL機能を評価する。

Outline of Final Research Achievements

FH homozygote is considered to be very high risk for atherosclerosis. Low HDL-C contribute in part for the increased atherosclerosis risk. Therefore, we aimed to elucidate kinetic pathophysiology for low HDL. We performed in vivo kinetic studies using endogenously-labeled stable isotope in 7 FH homozygotes. Kinetic studies revealed that fractional catabolic rates of apoA-I and apoA-II, major constituents of HDL, were markedly increased by about 50% as compared with control subjects with relatively unchanged synthetic rates. Therefore, low HDL levels was primarily due to increased catabolism in FH homozygotes. These findings may imply that therapy such as CETP inhibitors can normalized increased catabolic rates, thereby normalizing HDL-C in FH homozygotes. This may be a novel therapeutic strategy for treatment-resistant homozygous FH patients.

Academic Significance and Societal Importance of the Research Achievements

FH homozygotes needs early and effective treatment. The present study discovered that increased catabolic rate caused low HDL-C, another additive atheroscleritic risk. Based on our findings, we may develop a new therapy to nomalize catbolism to reduce the risk in FH homozygotes.
